Purpose of Data Provenance Clarification
This page explains the provenance of residential listing data referenced for Kampala. Its purpose is to define where the data originates, how it is formed, and what structural constraints follow from those origins. The focus is on interpretive discipline rather than analytical use.
Provenance is addressed to prevent assumptions that listing-derived information represents comprehensive residential reality.
Source Origins and Mediation Layers
The dataset consists of residential listings as exposed by digital platforms at a specific point in time. These listings are created by publishers and intermediaries who select attributes, categories, and location labels according to platform-supported fields.
Multiple mediation layers shape the data, including publisher intent, platform taxonomy, and technical publication rules. The dataset therefore reflects mediated representations rather than direct observation of housing assets.
Snapshot Construction and Temporal Limits
The data represents a snapshot captured at a single moment. It does not record prior states, subsequent changes, or duration of listing exposure. Listings may appear, change, or disappear independently of underlying residential conditions.
This snapshot construction limits temporal interpretability and precludes longitudinal inference.
Declared Attributes and Disclosure Constraints
All attributes within the dataset are declared by publishers or inferred through platform structures. Disclosure is selective and uneven. Absence of an attribute does not imply absence in reality, and presence does not imply standardization.
The dataset does not validate, normalize, or complete missing information.
Implications for Interpretive Use
Because the data originates from mediated listings, it must be read as a visibility layer. It cannot be used to infer housing stock, occupancy, ownership, or residential outcomes.
This provenance framework applies uniformly across all modules that reference listing-based information for Kampala.
